INTERLOOKING BRICK.

SPECIFICATION forming part of Letters Patent No. 468,840, dated February 16, 1892.. Application filed June 13,1891. Serial N 396,180- (No model.)

To all whom it may concern:

Be it known that I, LOUIS A. STEIGER, a citizen of the United States, residing at San Jos, in the county of Santa Clara and State of California, have invented a certain new, useful, and valuable Improvement in Interlocking Bricks, of which the following is a full, clear, and exact description.

My invention relates to improvements in bricks adapted especially for paving, although they may be employed 'to advantage for building purposes.

The object of the invention is the provision of a brick which will have interlocking tongues, whereby the tendency of the bricks to fall apart is prevented, and which can be made of any desired material and at a low price, and thus produce a brick which will be thoroughly useful and efficient. To attain the desired objects, the invention consists of a brick embodying certain novel features, herein illustrated, described, and specifically claimed.

In the accompanying drawings, Figure 1 represents a perspective View of a portion of pavement made of my improved brick. I ig. 2 represents a top view of one of my bricks. Fig. 3 represents a bottom view thereof. Fig. 4 represents a side view, and Figs. 5 and 6 represent end views, of my brick. Figs. 7, 8, 9, 10, and 11 represent Views of a modified form of my improved brick.

My improved brick is made of any preferred material, and in Figs. 1 to 6 is formed with the T-shaped end B and the reduced end 0 and on the sides with the inwardly-inclined faces D and the outwardly-inclined faces E, with the inclined ends F. Then the brick is laid in the sidewalk, the inclined edges or ends of one brick will fit snugly in against the inclined edges or ends of the other, and as all the edges of the brick are inclined the brick will either support or be supported on all sides. By this construction I provide a series of interlocking tongues or portions which cause the bricks to fit closely together and interlock, as clearly shown in Fig. 1, and by this construction the brick are capable of withstanding any hard usage or pressure without becoming separated or detached.

In the form of brick illustrated in Figs. 7 to 11 the sides and end of the brick are formed with similar.inclines to provide interlocking portions.

A brick constructed according to myinvention is durable and inexpensive, can be easily put together, and cannot possibly become detached, thus overcoming the defects existing in the present form of brick.

Having thus described my invention, what I claim is A block consisting of the integral partsll and O, the upper and lower faces of one part being in the same plane with the upper and lower faces, respectively, of the other, said upper and lower faces in each part being parallel and all the edges and ends of both parts being inclined, the longitudinal edges of one part inclining in one direction, and the longitudinal edges of the other part inclining in the opposite direction, substantially as set forth.

In testimony whereof I affix mysignature in presence of two witnesses.

' LOUIS A. STEIGER.
